Claude CodeOn this pageLast updated: 2026-06-08Even Hub tooling runs on Node.js. Run node -v: if it reports 20.x or 22+, jump to Install Even Hub tooling. Otherwise, start here.Target version: Node 20 LTS or 22+. The SDK declares engines.node = "^20.0.0 || >=22.0.0". Node 18 is not supported.
macOS - Homebrew
First install Homebrew if you don't have it:bash
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
Then:bash
brew install node@22
Windows - official installer
Download the LTS installer from nodejs.org and run it. Accept the option to add Node to PATH.
Linux - NodeSource
Distro packages are often outdated. Prefer NodeSource:bash
curl -fsSL https://deb.nodesource.com/setup_22.x | sudo -E bash -
sudo apt-get install -y nodejs
Prefer a version manager? (fnm / nvm / winget)A version manager lets you switch Node versions per project and avoids global-permission headaches.macOS / Linux - fnm or nvmbash
# fnm (fast)
curl -fsSL https://fnm.vercel.app/install | bash
# restart your shell, then:
fnm install 22
fnm use 22
# or nvm
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.7/install.sh | bash
nvm install 22
nvm use 22
Windows - fnm or wingetpowershell
# winget (ships with Windows 10/11)
winget install OpenJS.NodeJS.LTS
# or fnm via winget, then:
fnm install 22
fnm use 22
Verify
bash
node -v # v20.x or v22.x+
npm -v
Common gotchas
macOS - PATH after Homebrew. On Apple Silicon, Homebrew installs to /opt/homebrew. If node isn't found after install, ensure your shell profile sources it:bash
echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> ~/.zprofile
exec zsh
Windows - shimmed node.exe. Version managers (fnm/nvm-windows) expose node through a shim. This matters later: Windows Defender may block the shimmed node.exe inbound without prompting - see Hardware → Network & Firewall Setup.Linux/macOS - EACCES on global installs. If npm install -g fails with EACCES, do not sudo npm. Use a version manager (which installs into your home dir), or set a user-owned npm prefix:bash
npm config set prefix "$HOME/.npm-global"
export PATH="$HOME/.npm-global/bin:$PATH" # add to your shell profile
No global install? Use npx. The CLI runs without a global install:bash
npx @evenrealities/evenhub-cli qr --url "http://<your-lan-ip>:5173"
Handy on locked-down machines. A global install is faster for repeated use.PagerPrevious pageHardwareNext pageInstall Even Hub tooling
